    Abstract: MULTICHANNEL SPECTROPHOTOMETER A multichannel spectrophotomer as a single radiant energy source formed into a multiplicity of radiant energy beams which are each simultaneously intercepted by segments of a rotary source filter wheel, the spectral radiant energy output selected by each filter segment being directed into a separate source radiant energy conduit and transmitted to a remote sample station where a cuvette containing a sample to be analyzed is located, the radiant energy outputs of each cuvette being directed into a separate detector radiant energy conduit where each conduit is intercepted by a filter segment of a second rotating detector filter wheel identical to the source filter wheel and rotated in aligned synchronism therewith, the spectral radiant energy outputs of each segment of the detector filter wheel being further directed into a separate radiant energy detector and signal processing electronics associated with that sample station or spectrophotometer channel from which the radiant energy signal being detected and analyzed has been received. Central control, timing and display electronics are shared by each channel and may be overall programmed and controlled by computer. In one application involving the measurement of fluorescence, the filters of the detector filter wheel will be different from the filters of the source filter wheel so as to excite the sample cuvette at one wavelength and to measure fluorescent response at another.
